69= 7x + 5x + 9. Please help. I need this done by 12/4/2020
______________________________
1.) Swap sides so that all variable terms are on the left hand side:[tex]7x+5x+9=69[/tex]
- This is an optional step. I prefer the numbers to be on the left hand side, but it's not necessary.
Equation at the end of Step 1:
[tex]7x+5x+9=69[/tex][tex]69=7x+5x+9[/tex]2.) Combine 7x and 5x:[tex]7x+5x=12x[/tex]
- We combine like terms because there is 2 x's, and we need 1 x.
Equation at the end of Step 2:
[tex]12x+9=69[/tex]3.) Subtract 9 from both sides:[tex]9-9=[/tex] Cancels Out[tex]69-9=60[/tex]
- When solving problems like this, to get x alone you have to do the opposite of what you see.
- In this case, we have a positive 9. So to get rid of 9 we do the opposite: -9 on each side.
Equation at the end of Step 3:
[tex]12x=60[/tex]4.) Divide both sides by 12:[tex]12x[/tex] ÷ [tex]12=x[/tex][tex]60[/tex] ÷ [tex]12=5[/tex]- When solving problems like this, to get x alone you have to do the opposite of what you see.
- In this case, we have 12 being multiplied by x. So to get rid of the 12 we do the opposite: Divide by 12 on each side.

Suppose that u and v are vectors in R to the seventh power both of length 2 the square root of 2 and that the length of u − v is also2 the square root of 2 . Thenparallel-to u plus v parallel-to
Answer:
The angle between u and v is π/3 and parallel-to u plus v parallel-to = k*(u+v) (where k=const)
Step-by-step explanation:
In this question, one is expected to find the angle between u and v, and to get this angle, I will use the triangle formula.
|u-v|^2 = |u|^2 + |v|^2 - 2*|u|*|v|*cosθ
(2√2)² = (2√2)² + (2√2)² - 2(2√2)*(2√2)*cosθ
Expanding (2√2)² = (2√2)*(2√2) = 2*2*2 = 8
8 = 8 + 8 - 16*cosθ
8 = 16 - 16*cosθ
8 - 16 = -16*cosθ
-8 = -16*cosθ
cosθ = 8/16 = 1/2 = 0.5
θ = cos^(-1) (0.5)
θ = π/3
The angle between u and v is π/3 and parallel-to u plus v parallel-to = k*(u+v) (where k=const)

Answer:
The answer is 6/2 or 3/1.
Step-by-step explanation:
The equation for slope is (y2-y1)/(x2-x1). To find the answer, plug in two corresponding points. For example, [2.75-(-3.25)]/1-(-1). This will simplify into (2.75+3.25)/(1+1). After adding your numbers, you are left with 6/2.
Answer:
Step-by-step explanation:
the slope is the diference in y values /diference in x values of 2 points

Write the equation of the line with a slope of 5 and a y-intercept of (0, -3)
Answer:
y = 5x - 3
Step-by-step explanation:
equation of a straight line is y = mx + b where m=slope and b=y-intercept
in this case m=5 and b= -3
y = mx + b
y = 5x - 3
which sequence of transformations is required to create the image of rooftop 2 from the pre-image of rooftop 1-please explain!!
9514 1404 393
Answer:
F or J
Step-by-step explanation:
The final two transformations in all choices are ...
translation eastrotation 90°If the rotation is clockwise, the translated figure must have a shape like this:
┌
Such a shape can be obtained only by reflection across the east-west street. As the first attachment shows, translation east of the reflected figure, then rotation 90° CW will locate Rooftop 2 approximately as shown in the given drawing.
__
If the rotation is counterclockwise, the translated figure must have a shape like this:
┘
This shape can only be obtained by reflection across the north-south street. That reflection and subsequent translation will leave the figure north of the east-west street. A 90° CCW rotation about a suitably chosen point can place it south of the east-west street, in the location shown in the given drawing.
__
The first attached figure was obtained by the sequence described in choice F. The second attached figure was obtained by the sequence described in choice J. The sequence of transformations is shown as red after the reflection, purple after the translation east, then blue after the rotation about the indicated point.
Both F and J are appropriate answer choices.
_____
Additional comment
It can be proven algebraically that choices F and J can both produce exactly the same transformation for some combination of translation and center of rotation. It seems likely that one of these answers will be preferred by your computer. You may want to discuss this question with your teacher.

Which is an equation of the line with a slope of 2/3 passing through the point (4, -1)?
Answer:
y + 1 = (2/3)(x - 4) is the desired formula
Step-by-step explanation:
Start with the general point-slope formula y - k = m(x - h), where (h, k) is the given point and m is the given slope.
Given the point (4, -1), we substitute 4 for h in this general formula, -1 for k and 2/3 for m:
y + 1 = (2/3)(x - 4) is the desired formula.
The equation of the line with a slope of 2/3 passing through the point (4, -1) should be considered as the [tex]y + 1 = (2/3)(x - 4)[/tex]
Calculation of the equation of the line :Since
we know that
The formula for general point slope should be
y - k = m(x - h),
where (h, k) is the given point and m is the given slope.
Since the point (4, -1),
So here we substitute 4 for h in this general formula, -1 for k and 2/3 for m:
Therefore, The equation of the line with a slope of 2/3 passing through the point (4, -1) should be considered as the [tex]y + 1 = (2/3)(x - 4)[/tex]

What does it mean to translate an x and y coordinate into a composition?
Answer: When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation. The figure is translated from one position to another. Example 1: A point is located at (3, 7) on the coordinate plane. In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting, or changing its size. This is done by moving the vertices of the figure to the prescribed number of spaces on a coordinate plane and then drawing the new figure. There are four main types of transformations: translation, rotation, reflection, and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

Can the sides of a right triangle have sides the lengths of 48.5ft, 32.5ft, and 30 ft?
Answer:
No, you can't have a right triangle with the sides 48.5ft, 30ft, 32.5ft.
Step-by-step explanation:
48.5 + 30 + 32.5 = 111 ft
Triangle's total sides: 180.
One side has to be equal to 90ft.
Answer:
Step-by-step explanation:
32.5²+30²=1056.25+900=1956.25
48.5²=2352.25≠1956.25
so it is not a right angled triangle.
